Scratch on inside of glass tank

[rdevoe11]

It's maybe 2 inches long, resembles a strand of hair stuck to the inside glass. I can feel it with my fingernail.

Just wondering if this is something I should be concerned about, or rather just keep an eye on.

Thanks!

Nothing to be concerned about.
The hard part is keeping scratches clean. They become more visible as algae grows in them, and depending how deep they are they can be really tough to clean.
I just had to replace my 200g tank because the front pane was so scratched up. DSA used some insanely soft low iron glass.
Other than being an eyesore, no worries.

ok good..the concentration of algae growth is how I discovered it, but it doesnt appear to be too deep as it cleaned very easily..thanks!
